Description

A traffic light system that allows the driver to clearly recognize the type and duration of the ongoing traffic signal by dual displaying the current traffic signal with multiple displays and displaying the remaining time in seconds. {TRAFFIC LIGHT SYSTEM THAT ALLOWS DRIVER TO CLEARLY RECOGNIZE TYPE AND DURATION OF ONGOING TRAFFIC SIGNAL BY DISPLAYING CURRENT TRAFFIC SIGNAL IN DUAL AND DISPLAYING REMAINING TIME IN NUMBERS ON A PLURALITY OF DISPLAYS}

The present invention relates to a traffic light system that allows the driver to clearly recognize the type and duration of the ongoing traffic signal by displaying the current traffic signal in dual form with a plurality of displays and displaying the remaining time in seconds. .

In the conventional traffic light system, the driver's traffic light placed on the rod of the column has only one display panel, and the display panel is divided into multiple zones to display the current traffic signal among traffic signals such as red, yellow, blue, and left turn. Only indicated.

However, this conventional traffic light system provides only one angle of view to the driver, so there is a problem in that drivers at a specific location (for example, the driver of a passenger car behind a truck) cannot properly recognize the signal. In other words, the existing traffic light system had a problem where it was difficult to recognize the signal due to a shadow zone for drivers at a specific location. In addition, there was a problem of not accurately recognizing the duration of the current signal because the driver could only recognize the remaining time by flashing. In particular, when the blue signal changed to yellow, there was no warning such as flashing, so the driver could not recognize the remaining time of the current signal by blinking. There is a high risk of an accident if you try to pass quickly on the sidewalk, and if you pass slowly, there is a high possibility of arguments/retaliation due to the driver of the car behind you.

Hereinafter, the traffic light system of the first and second embodiments of the present invention will be described with reference to the drawings. Figure 1 is a perspective view showing a general traffic light system, Figure 2 is a perspective view showing a traffic light system of a first embodiment of the present invention, and Figure 3 is a perspective view showing a traffic light system of a second embodiment of the present invention.

First, a general traffic light system commonly applied to the traffic light systems of the first and second embodiments of the present invention will be described. The traffic light system includes a column (1) extending vertically from the ground, a rod (2) extending horizontally from the column (1), and a traffic light (3) disposed on at least one of the column (1) and the rod (2). , may include a controller module (4) that electronically controls the traffic light (3). In this case, the traffic light 3 can be operated by a control signal from the controller module 4 and multiple traffic signals (red signal, blue signal, yellow signal, left turn signal, etc.) can be displayed. Meanwhile, the traffic light 3 can be divided into a pedestrian traffic light mainly placed on the column 1 and a driver traffic light mainly placed on the road 2. Hereinafter, the traffic light 3 will be described based on the driver traffic light. However, it is not limited to this and can also be applied to pedestrian traffic lights.

Hereinafter, the traffic light system of the first embodiment of the present invention will be described. The traffic light system may be characterized in that the traffic light 3 includes a first display 3-1, a second display 3-2, and a third display 3-3.

In this case, the first display 3-1 can be controlled by the controller module 4 to display a plurality of traffic signals selected according to time. For example, the first display 3-1 has a red signal area, a blue signal area, a yellow signal area, and a left turn signal area, and the red signal area is changed at the time of the red signal by the timer input to the controller module 4. The blue signal area may emit light at the time of the blue signal, the yellow signal area may emit light at the time of the yellow signal, and the left turn signal area may emit light at the time of the left turn signal.

The second display 3-2 may be arranged on one side of the first display 3-1, but the position of the second display 3-2 is not limited to this. The second display 3-2 is controlled by the controller module 4 to display the traffic signal currently displayed on the first display 3-1 among the plurality of traffic signals. That is, in the second display 3-2, the red signal area, blue signal area, yellow signal area, and left turn signal area can be arranged to overlap and are in the same area at the time of the red signal/blue signal/yellow signal/left turn signal. The corresponding signal may be displayed.

As described above, the signal currently in progress on the first display 3-1 is linked and independently displayed on the second display 3-2, so in the traffic light system, the signal currently in progress is provided in the form of a dual screen at various angles of view. This allows drivers in the dark to clearly recognize the signal.

The third display (3-3) may be arranged on the other side of the first display (3-1) and adjacent to the second display (3-2), but the location of the third display (3-3) is It is not limited to this. The third display (3-3) is controlled by the controller module (4) and displays the remaining time of the currently in progress signal in numbers in seconds. In particular, the remaining time for yellow traffic signals that generally do not have flashing notice is displayed to the driver. By clearly recognizing it, you can provide criteria for judging whether to proceed or stop. Accordingly, the traffic light system has the advantage of solving the problem of conflicts with cars behind due to misjudgment due to non-recognition of the remaining time of yellow traffic signals, etc.

Hereinafter, the traffic light system of the second embodiment of the present invention will be described. The traffic light system is characterized in that it additionally includes an auxiliary traffic light (5). The auxiliary traffic light 5 is in the form of an LED film (e.g., a film in which LED elements are mounted on a coated flexible printed circuit board), and can be disposed wrapped around the outer peripheral surface of at least one of the column 1 and the rod 2. . In this case, the auxiliary traffic light (5) can cover about 2/3 to 1.5/3 of the outer peripheral surface of the column (1) or rod (2), and is tied and fixed by an auxiliary string such as a tie or steel band. However, the method of fixing the auxiliary signal code 5 is not limited to this.

The auxiliary traffic light 5 is linked to the electronic control signal through which the controller module 4 controls the traffic light 3 and can display the same traffic signal as the traffic signal currently displayed by the traffic light 3.

In this case, the linked control of the auxiliary traffic light (5) can be implemented in various ways. For example, a hub is connected to the main control unit of the controller module (4) and the signal that controls the traffic light (3) is directly transmitted to the auxiliary traffic light ( It can be implemented by transmitting to 5), but is not limited to this. Meanwhile, in this case, the hub and the auxiliary traffic light 5 can be connected by branching the cable line that electrically connects the main control unit and the traffic light 3, but the connection is not limited to this.

Accordingly, the entire film of the auxiliary traffic light 5 can emit red when the traffic light 3 is a red signal, and the entire film can emit blue when the traffic light 3 is a blue signal, and the entire film can emit blue when the traffic light 3 is a blue signal. When the traffic light (3) is a yellow signal, the entire film can emit yellow light, and when the traffic light (3) is a left turn signal, it can emit light to display an arrow.

Furthermore, a sub-control unit is provided to control the auxiliary traffic light (5) separately from the main control unit of the controller module (4), and is connected to the hub to be independent of the traffic light (3) and to be used in child protection areas or black ice. By displaying an image of a section or linking it with the traffic signal of the traffic light (3), the same traffic signal can be displayed while at the same time displaying danger/public interest signals such as a child protection zone or black ice section in one area.

Hereinafter, a traffic light system of a modified example of the present invention will be described. The traffic light system of the modified example of the present invention is characterized in that the controller module 4 itself prevents wild animals from entering.

The controller module 4 includes a case (not shown), a main control unit placed inside the case to control the traffic light 3, and a main control unit placed inside the case and linked with the signal of the main control unit to control the auxiliary traffic light 5. A hub that transmits control signals, an infrared sensor that is placed inside/outside the case and generates an infrared image, a camera sensor that is placed inside/outside the case and generates a visible light image, and is placed inside/outside the case. It may include a control module that controls the infrared sensor and the camera sensor and receives infrared images and visible light images, and an oscillator that oscillates under the control of the control module.

The control module can process infrared images to determine whether there is a living organism and process visible light images to determine living organism information. In this case, the control module turns on the infrared sensor and turns off the camera sensor, determines that a living organism exists from the infrared image, and then turns on the camera sensor. In other words, the control module normally operates only the infrared sensor to analyze the thermal image, determines that a living organism exists inside the case when the temperature of the living organism is detected, and then turns on the camera sensor only when a living organism exists inside the case. By creating a visible light image and analyzing the clear visible light image, information on living organisms can be determined in detail. In other words, camera sensors with high power consumption can increase power efficiency by turning them on and operating only when necessary.

Biological information may include, but is not limited to, “species of living organisms (wild animals), etc.” The database of the control module stores data on the temperature range of the living organism, and when thermal image data about the temperature range of the living organism stored in the database is detected from the infrared image of the infrared sensor, the control module detects the presence of living organisms inside/around the case. It can be judged that In addition, data on the species of wild animals according to each image is mapped in the database of the control module, and the image stored in the database is matched with a specific image of the visible light image of the camera sensor, and then the wild animal species mapped to the image is mapped. Biological information can be calculated using data on species and size.

In this case, the oscillator may be an ultrasonic oscillator, and the frequency intensity and bandwidth may be controlled and operated according to the biological information determined by the control module (for example, snakes and rats have different audible ranges, so the oscillators have different frequency intensity and bandwidth). should work). Accordingly, it is possible to prevent wild animals, etc. from entering the case, damaging expensive electrical components (central processing unit components) and paralyzing the control system.

Furthermore, the controller module 4 may additionally include a 3D camera (not shown, for example, LIDAR; generating a 3D depth image) disposed inside/outside the case in addition to the infrared sensor and camera sensor.

In this case, the control module normally turns on the infrared sensor, turns off the camera sensor, 3D camera (not shown), and oscillator, determines that a living organism exists from the infrared image, and then turns on the camera sensor.

Next, the control module can analyze the visible light image to determine biological information. In this case, the organism information may include “species and speed of the organism (wild animal), etc.,” but is not limited thereto. In this case, the control module can measure the speed of the wild animal per unit time by calculating the change in the position of the image of the creature per unit time in the visible light image.

If the speed of the wild animal is below a certain value, the control module can oscillate the oscillator at a frequency intensity and bandwidth that matches the species of the wild animal.

In contrast, if the speed of the wild animal is above a certain value, the control module can turn on the 3D camera to determine the volume of the creature (not shown). In this case, if the volume of the organism is above a certain value, the control module does not operate the oscillator until the speed of the wild animal falls below a certain value. Then, when the speed of the wild animal falls below a certain value, the control module switches on the frequency matching the species of wild animal. The oscillator can be driven to oscillate with any intensity and bandwidth. In contrast, the control module can operate the oscillator to oscillate at a frequency intensity and bandwidth that matches the species of the wild animal, regardless of the speed of the wild animal, if the volume of the organism is less than a certain value.

In other words, if the speed of a wild animal is above a certain value, the wild animal suddenly enters the inside of the case or is confused in a narrow space. If the oscillator is suddenly activated, the confusion increases and it moves around the inside of the case at a faster speed, causing great damage. There is a possibility of causing

To prevent this, the control module determines the size of the wild animal using a 3D camera (not shown), and then operates the oscillator immediately because if the size is small, the risk of damage is low even if it moves around at high speed and it is important to send it out as soon as possible. If the size is large, rather than suddenly activating the oscillator, the speed can be reduced to a certain extent and then the oscillator can be activated to induce the wild animal to carefully escape from the case in a calm state.

Furthermore, the controller module 4 may further include a speaker (not shown) controlled by the control module. The speaker is normally turned off by the control module, and can be activated by the control module when the time for which the speed of the wild animal is above a certain value is longer than a certain value. In this case, nearby managers can sense that a wild animal is shaking inside the case and dispatch the case urgently.

Furthermore, the controller module 4 may further include a light source module (not shown) controlled by the control module. The light source module is normally turned off by the control module, and after the control module determines that a living organism exists from the infrared image, it is turned on to emit visible light to the inside/outside of the case. Accordingly, the camera sensor can generate an accurate visible light image by receiving abundant light from the visible light of the light source module. In addition, if the control module determines that the speed of the wild animal is less than a certain value, the light source module may remain on for a first time and then turn off, and if the control module determines that the speed of the wild animal is greater than a certain value, the light source module may It may remain on for a second time longer than the first time and then turn off. If the speed of a wild animal is above a certain value, there is a need to continuously track the speed of the wild animal, and accordingly, clearer visible light images need to be generated for a longer period of time from the camera sensor.

Above, embodiments of the present invention have been described with reference to the attached drawings, but those skilled in the art will understand that the present invention can be implemented in other specific forms without changing its technical idea or essential features. You will be able to understand it. Therefore, the embodiments described above should be understood in all respects as illustrative and not restrictive.
